DP627 – 4 Lane DP Tcon

Direct Drive LCD Timing Controller with 4-Lane DisplayPort Receiver

The DP627 is a panel timing controller (Tcon) developed specifically for a PC Direct Drive Monitor (DDM). It includes a DisplayPortTM receiver and supports display resolutions up to 1920 x 1200 (Full HD) with up to 30 bit color. It is designed to be mounted on the LCD panel, elliminating the seperate monitor controller board within the monitor to reduce monitor size and cost.

The DP627 provides pixel data through a mini-LVDS interface with programmable timing to support a variety of LCD panel designs. The device includes audio support through both I2S and S/PDIF digital outputs. The DP627 de-spreads the DisplayPort SSC Link clock, and can also add SSC on the mini-LVDS output.
A scaler function is included to provide a full screen display for lower resolution video that may occure during Safe Mode or other DOS modes. Full screen display is supported for input modes such as 640×480, 800×600, and 1024×768.

For the support of display resolution above 1920×1200, please refer to the DP628.
